Portrait of John Bardeen

This mosaic is the second in a series entitled “Rendered Obsolete”. The mosaic is made from electronic parts which in modern electronics have been replaced by the transister and other more modern devices, thus these parts have essentially been rendered obsolete by Bardeen’s own invention. The first in the series is a mosaic of J.R. Schrieffer, co-recipient with Bardeen of the 1972 Nobel Prize in Physics.From Wikipedia:
John Bardeen was an American physicist and electrical engineer, the only person to have won the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity known as the BCS theory.

The transistor revolutionized the electronics industry, allowing the Information Age to occur, and made possible the development of almost every modern electronic device, from telephones to computers to missiles. Bardeen’s developments in superconductivity, which won him his second Nobel, are used in magnetic resonance imaging (MRI).
In 1990, John Bardeen appeared on LIFE Magazine’s list of “100 Most Influential Americans of the Century.”
